King of the Swing Baseball & Softball Hitting Trainer
The King of the Swing is a hitting trainer built to teach hitters how to create power from the ground up. It focuses on backside loading, lower-half engagement, directional force toward the pitcher and efficient energy transfer through the swing.
The trainer gives instant audible feedback when the hitter reaches the selected force threshold, helping players feel whether the lower half is truly engaged instead of relying only on verbal cues. Used by 28 MLB Organizations. The King of the Swing was developed around the same lower-half training concepts used at the highest levels of baseball.
Key Features & Hitting Benefits
Key Feature
What It Does
Why Hitters Care
Instant audible feedback
Produces a clear sound when the hitter reaches the selected force threshold.
Gives immediate confirmation that the lower half is loading and driving correctly.
Progressive spring resistance
Resistance can be increased as the athlete improves.
Allows young hitters to learn the movement and advanced hitters to challenge power production.
Angled hitting platform
The platform angle helps the hitter feel backside loading.
Reinforces a stronger load before energy is transferred forward.
Directional-force training
Encourages force toward the pitcher rather than simply spinning around the back side.
Helps reinforce a more efficient lower-half pattern through the swing.
Ground-force focus
Teaches the athlete to create energy through the legs and transfer it up the kinetic chain.
Supports bat-speed and power training without making the drill purely upper-body dominant.

How King of the Swing Works
1. Learn the load. Start without chasing maximum resistance and feel how the backside loads against the angled platform.
2. Create force from the ground. Use the legs and lower half instead of beginning the swing only with the hands and upper body.
3. Transfer toward the pitcher. Train directional force instead of simply spinning around the rear leg.
4. Listen for the audible signal. The trainer tells the hitter immediately when the selected force threshold is reached.
5. Add resistance as the movement improves. Progressively increase spring tension to challenge stronger hitters.
Why This Is Different from a Normal Swing Drill
Many hitting drills tell a player what the lower half should do. King of the Swing gives the athlete a physical task with immediate feedback. The goal is to connect the feel of loading and driving the ground with the swing sequence so the movement can be repeated without a coach having to say “use your legs” every rep.
Who Should Use King of the Swing?
Youth hitters learning to use the lower half
Travel players working on stronger loading patterns
High school hitters developing power and bat speed
College hitters refining sequencing and directional force
Professional hitters challenging movement quality at higher resistance
Hitting instructors building objective feedback into lessons

Great for down time at practice!
The guys on my team love this rebound net! As coaches know, some guys get warmed up before others and without direction, they will start horse playing and goofing off. With a 10u team, the horse play can be contagious and all but ruin a practice. I set the rebound net up at the backstop and the guys make their own competition with it while waiting for the later arrivals to get loose. It keeps the guys warmed up while having fun! Best of all, it helps with their reaction times and fielding a variety of different balls. The 32" is good for them to practice accuracy while throwing and also returning the ball different each time depending on where they hit the net. We do also use in other practice drills but this thing is extremely valuable in keeping the guys active and independently practicing while we set up that days drills. We'll always keep one on the field! It seems to be very well built and is definitely getting the reps in with no show of wear. If any coaches are thinking about getting this, you won't be sorry. Real coach, real review!

26 x 26 rebounder
I am in physical therapy as a result of rotator cuff surgery. I was looking for an exercise to supplement the exercises at PT. When I could finally come over the top to throw a baseball/softball I found the rebounder. It is EXACTLY what I need to get back in shape. It's the perfect size and provided the necessary rebound for my exercise/training regimen.

Plyo wall
The plyo wall is excellent. Well built and allows us to do all our weighted throws. I recommend anyone looking for a quality portable plyo wall to buy from Maximum Velocity Sports.

Best quality you can find.
If you grew up with an old school pitchback, you know how much the quality has suffered from the ones you'll find on amazon. Yea, this one has a premium price, but it's construction is highly superior. You get a sharper bounce too. If you're looking to find a rebounder that can stick with you through all ages, then this is the one to buy. Buy one of these for the rest of your players days or buy the cheap one on amazon...
Definitely don't do like I did and buy the one on amazon first to realize you should have invested in the best to begin with.

Daily use!
The 3X3 rebounders are great, we have started using them every day and they go to every practice. We enjoy finding new ways to use the rebounders in softball drills. Everything from catchers working on transfers to outfielders working on drop steps!
